INTEGRATED PROJECT DELIVERYIntegrated Project Delivery (IPD) is a project delivery

approach that integrates people, systems, business

structures and practices into a process that

collaboratively harnesses the talents and

insights of all participants to reduce waste and

optimize efficiency through all phases of

design, fabrication and construction.

SPRING QUARTER

Trends Discovered:

1. Many tasks scheduled as sequential were forced to

become parallel due to the fast-track nature of the project

and increased interaction among disciplines

2. Between April 6th and 11th, tasks took A LOT longer than

expected

3. Visual representation of progress interaction is limited to

larger, broader tasks to avoid clutter

Our JourneyA E MEP C

Atlantic team


SPRING QUARTER

IPD Lessons Learned:

Establishing an extensive TO-DO list at the beginning

helps to reinforce and clarify project requirements

Nothing goes as originally planned – instead, it is

important to always know what still needs to be finished

and to constantly replan...and then replan again

Planning estimated finish dates should incorporate

many iterations of design


Atlantic team

IMPROVEMENTS FROM

WINTER QUARTER

• Level of communication

• Greater bonding

• Communicated in shorter intervals

• Greater interaction with mentors

Improved from winter quarter


A E MEP C

Atlantic team

LESSONS LEARNED

• Just-in-time sequencing of tasks.

• Direct communication makes everything

clearer.

• Be more understanding and open-minded

to new ideas.

• Communicating across disciplines with a

common language.
